Apple will fix it in iOS 4.3.4 firmware some day. Fortunately Comex has already released a patch for his JailbreakMe 3.0 exploit to protect already jailbroken devices from any malicious use of the exploit.

The package called 'PDF Patcher 2' can be downloaded and installed from Cydia. To jailbreak please use our step-by-step instructions.

Apple does not allow users to install iOS version that is older than the latest released version. There is a workaround for this restriction. Users who have saved SHSH blobs using Cydia or TinyUmbrella for particular iOS version and particular iDevice can restore to this iOS.

According to the iPhone Dev-Team, Apple is now making this process much more difficult with iOS 5. This means that current process will not work with iOS 5. But users who saved 4.x SHSH keys will be able to restore to 4.x.

Today Comex revealed in his Twitter that he found a way to drastically decrease the time it takes to jailbreak and learned how to utilize unionfs and thus get rid of the Cydia's 'Reorganizing FileSystem' process.

New approach will reportedly be used in his next jailbreak for iPad 2.

If you want to know more details on Comex's new approach, check his long tweet.

Earlier Musclenerd stated that it won't be necessary to move Apple apps anywhere if unionfs will be used. That also means that apps will keep their entitlements and thus simplify the sandboxing problem.

Last year we told about Greg Hughes, who created the "Wi-Fi Sync" app, which allows to synchronize your iOS-device with iTunes wirelessly. After Apple's rejection the developer sent it to the Cydia Store instead. Since then the app was sold over 50,000 times. But as you know, this week Apple unveiled that it made Wi-Fi Synchronization with iTunes an inbuilt feature in iOS5. In response Hughes decided to accuse the company in ripping his work.Read the rest of this entry »

For now the jailbreak is tethered (you have to run redsn0w each time you reboot) and available for Mac OS X only. It will not activate your device, so you need have registered UDID. iPhone 3GS users with 06.15 baseband: redsn0w will get you past the iTunes restore error. This redsn0w will probably work on future versions of iOS 5.
